Nighthawk AC1900 WiFi VDSL/ADSL Modem Router Model D7000
By default, this check box is selected. You can disable or enable UPnP for automatic device configuration. If
the Turn UPnP On check box is cleared, the modem router does not allow any device to automatically control
router resources, such as port forwarding.
6. Enter the advertisement period in minutes.
The advertisement period specifies how often the modem router broadcasts its UPnP information. This value
can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points
detect current device status at the expense of more network traffic. Longer durations can compromise the
freshness of the device status but can significantly reduce network traffic.
7. Enter the advertisement time to live in hops.
The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. Hops are the
steps a packet takes between routers. The number of hops can range from 1 to 255. The default value for the
advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some
devices are not being updated or reached correctly, it might be necessary to increase this value.
8. Click the Apply button.
The UPnP Portmap Table displays the IP address of each UPnP device that is accessing the modem router
and which ports (internal and external) that device opened. The UPnP Portmap Table also displays what type
of port is open and whether that port is still active for each IP address.
9. To refresh the information in the UPnP Portmap table, click the Refresh button.
